Guix,
When visiting localhost:631/admin, the server appears to freeze
(blank page). However, exactly 2 minutes later content is served
and buttons like ‘Find New Printer’ [appear to] work without
delay.
Some error_log debug output below. Note the 2 neat 1-minute
time-outs.
It's likely that this is an upstream bug (but not quite this [1]).
I'll try upgrading CUPS and gathering more infos.
Kind regards,
T G-R

I've pushed some patches I've been using since ‘forever’ to
core-updates. They simply remove the entire right-hand ‘Server’
form, and short-circuit the logic behind it that caused the long
delays.
An older work-around I tried was to simply link to the store
cupsd.conf in /etc/cups. This solves the immediate problem, and
even allows viewing (not editing) a few settings in said form.
It's an option for those who can't wait for core-updates to be
merged (don't forget to delete it next year… :-).
However, doing so merely hides the fact that this code is broken
with -c FILE by effectively circumventing the option in a very
sneaky way. A step back, not forward.
Kind regards,
T G-R
